BACKGROUND Studies show great variability in the prevalence of hyperopia among children. This study aimed to synthesize the existing knowledge about hyperopia prevalence and its associated factors in school children and to explore the reasons for this variability. METHODS This systematic review followed PRISMA guidelines. Searching several international databases, the review included populati...

BACKGROUND Hyperopic undercorrection is a common clinical practice. However, less is known of its effect on the change in refractive errors and emmetropization throughout the later years of childhood. OBJECTIVES To evaluate the effect of spectacle correction on the change in refractive errors in hyperopic children less than 12 years of age with or without strabismus. DATA EXTRACTION A retro...

PURPOSE To determine the efficacy, stability, and predictability of refractive surgery for hyperopia using four different procedures: photorefractive keratectomy (PRK), laser in situ keratomileusis (LASIK), implantation of a phakic intraocular lens (PIOL), and removing the transparent lens with IOL implantation. METHODS We operated on 184 eyes with hyperopia; 56 eyes had less than +2.00 D (lo...

PURPOSE To evaluate the safety and efficacy of the ALLEGRETTO WAVE excimer laser system (WaveLight Laser Technologie AG, Erlangen, Germany) in LASIK for hyperopia and hyperopic astigmatism. METHODS One hundred twenty consecutive LASIK cases for hyperopia with or without astigmatism treated with the ALLEGRETTO WAVE excimer laser were prospectively evaluated up to 12 months postoperatively. Pat...

PURPOSE To describe the prevalence of hyperopia and associated factors in a representative sample of Australian schoolchildren 6 and 12 years old. DESIGN Population-based cross-sectional study. PARTICIPANTS Schoolchildren ages 6 (n = 1765) and 12 (n = 2353) from 55 randomly selected schools across Sydney. METHODS Detailed eye examinations included cycloplegic autorefraction, ocular biomet...

AIMS High hyperopia constitutes the majority of refractive errors in large scale visual screening at preschool ages. The authors aimed to assess the validity of the Retinomax hand held refractor to detect high hyperopia in a refractive screening performed without cycloplegia and carried out on children aged 9-36 months. They considered +1.5 D of manifest hyperopia to be the threshold value and ...

PURPOSE To investigate the association between concomitant esotropia or concomitant exotropia and refractive error in preschool children. METHODS A population-based sample of 5831 children aged 3 to 6 years was selected from all kindergartens in a representative county (Yuhuatai District, Nanjing, Jiangsu Province) of Nanjing, China. Clinical examinations including ocular alignment, ocular mo...

BACKGROUND Progressive hyperopia is a common complication following radial keratotomy. METHODS Ten eyes of ten consecutive patients with hyperopia after radial keratotomy between +1.75 and +4.00 diopters (D) were treated with the hyperopia module of the Nidek Model EC-5000 excimer laser. The mean preoperative uncorrected visual acuity was 0.38 (20/60+). RESULTS After excimer laser photorefr...

Purpose: To describe the prevalence of hyperopia and associated factors in a representative sam Australian schoolchildren 6 and 12 years old. Design: Population-based cross-sectional study. Participants: Schoolchildren ages 6 (n 1765) and 12 (n 2353) from 55 randomly selected schools acr Sydney. Methods: Detailed eye examinations included cycloplegic autorefraction, ocular biometry, cover testi...

PURPOSE To assess choroidal thickness (CT) variation according to refractive errors using enhanced-depth imaging optical coherence tomography. METHODS Eighty-nine eyes (in 89 children) <±6 diopter were categorized into three groups: hyperopia, emmetropia, and myopia, according to refractive error, and underwent choroidal scans using enhanced-depth imaging-optical coherence tomography. CT was ...
